Use the CPUFreq governor 'blu_active' as default. This allows
you to get a full dynamic cpu frequency capable system by simply
loading your cpufreq low-level hardware driver, using the
'interactive' governor for latency-sensitive workloads.

'blu_active' - This driver adds a dynamic cpufreq policy governor
designed for latency-sensitive workloads.
This governor attempts to reduce the latency of clock
increases so that the system is more responsive to
interactive workloads.
To compile this driver as a module, choose M here: the
module will be called cpufreq_blu_active.
